SPECIFICATION forming part of Letters Patent No. 480,939, dated August 16, 1892.

Application iilcd July 29, 1,891. SerialNo. 401,078. (No model.)

T all whom t may concern:

Be it known that we, JOHN H. SHULL andK GEORGE S. DOENEY, citizens of the United States, residing at Findlay, in the county of Hancock and State of Ohio, have invented certain new and useful Improvements in Conveyers for Tiles, dac., of which the following is a specification.

The invention relates to endless-belt conveyers adapted for use in connection with the manufacture of tile, brick, dac.; audit has for its object to provide an improved means for the necessary transportation of tile or brick from one part of the plant to another part of the plant during the process of manufacture.

The invention consists in certain novel features in the construction of such a device, which will be particularly pointed out in the claims, being iirst fully described with reference to the accompanying drawings, in which- Figure 1 is a plan of a device embodying our invention, the same being foreshortened by the removal of a portion between the ends, but which may be of any desired length. Fig. 2 is-a side elevation of one end of the same. Fig. 3 is an end elevation of the end frame and driving mechanism without the chains which constitute the endless belt. Fig. 4is a similar view of one of theintermediate frames.

' and the pallets are provided with friction-rollers 1718 for running on said rails. friction-rollers are each supported on the pal- The inner rail 16 has a V:narrow tread and the inner roller 18 is mount- Fig. 5 is a perspective view'of one of the pallets, its connecting-stem, the friction-rollers, and the combined scrapers and safety-stops secured thereto.V 1'

1 represents one of the two frames located at the respective ends of the conveyer, and 2 one of a number of frames which are placed at certain intervals along the route and between the end frames. One of the end frames carries the horizon tal power-shaft 3, (see Figs. 2 and 3,) to which power may be applied from any convenient source. Both of the end frames are provided with vertical shafts 4, mounted in suitable bearings on said frames, and these shafts 4 carry on their upper ends bevel gear-wheels 5, which intermesh .Withcorresponding pinions 6 on opposite ends of a long horizontal shaft 7, which extends from end to end of the machine. The shaft 7 has bearings 24 in the end frames and may also have bearings 24 in soule or all of the intermediate frames, as may be necessary.

' endless belt. the endless belt, and the chains of said belt lets by hangers 19.

Beneath the bevel-gears 5 on each of the shafts 4 are mounted two horizontal sprocket-wheels 8 for supporting and driving the endless chains 9, which travel in a horizontal plane. 'lhe vertical shaft 4 of the drive end of the machine is further provided with a pinion 10, which engages a pinion 11 on the drive-shaft 3. From so much of the description it will appear that power applied to shaft 3 will be transmitted through one of the vertical shafts 4 to the horizontal shaft 7 and thence to the vertical shaft4 on the opposite end of the machine, so that both vertical shafts are rotated with their sprocket-wheels and the endless belt driven from both ends of the machine simultaneously, which is a very important feature if a long conveyor is employed.

l The belt is constructed of two endless chains 9.; The `b elt carries above ita number of horizontal-pallets or tables 12, which are provided with stems 13, and these stems are secured by bolts 14 to the outer sides of corresponding linksof the upper and lower chains of the The pallet is thus secured to are accurately and permanently spaced.

In Order to insure the steady travel of the pallets 12 and to support the chains along the route, rails 15 16 are mounted on the frames The outer ed in a hanger 20, which has projecting ends 2lfor engagement on opposite sides of the rail 16 and prevention of displacement of the roller 18. The entire belt is stayed against serious transverse vibration. The outer rail Y15 and its corresponding roller 17 are made broad, and these simply serve as a traveling support for the outer side of the pallet. The broad treads of. this rail and wheel' are also designed for permitting the necessary transverse movement of the belt when rounding the ends without losing the bearing.

22 represents the combined track-clearers and safety-stops located on the pallets.- They are designed for the purpose of clearing the rails of any obstacle, such as clay, which may drop upon the track, and being placed on diagonally-opposite corners and made to extend just above the horizontal plane of the rollers they operate as stops to prevent the tipping of the pallets beyond a certain limit, either in a longitudinal or transverse direction.

For the accommodation of the tracks and longitudinal shaft upon the intermediate frames each intermediate frame is provided with the central standard 23, having the shaftbearing 24 at top, and the cross-bar 25 for the inner track and the side posts 26 for the outer track. The intermediate frames may be constructed rigidly, but inexpensively, by the use of diagonal braces 27, the spacing-bars 28, and bases 29.

30 represent boards placed between the end frames and the adjacent frames for bracing the bearings of shaft 7 and insuring engagement of pinions 5 and A6.

While we have thus minutelydescribed the construction of the frames, it is obvious that any `suitable support might be used with advantage. If desired, an additional support 3l may be employed for the shaft 3.

The chain is composed of acombinationof links 32 and strap 33, the former being adapted to receive the pins Bton the sprocketwheelsand the latter being adapted to conform to the periphery of the wheel between the pins, as well as to afford available space for the attachment of the stems of the pallets.

In using the device the tile or bricks are placed on the pallets at one end and removed therefrom at the other end by hand, as they are in a semi-plastic state. lf the operator at the delivery-end fails vto remove one or more, they simply pass around andare removed the next time.

While the device isshown running i-'n a single straight line, it is obvious that it may be extended and adapted to round curves by the employment of an increased number of end frames and sprocket-Wheels.

Having thus described our invention, the following is what we claim as new therein and desire to secure by Letters Patent:

l. The combination of supporting-frames, the vertical shafts, a pairof horizontal sprocket-wheels on each of the shafts, a conveyorbelt consisting of two endlesschains connecting the sprocketwheels, a horizontal shaft and gear-wheels connecting theverticalshafts, driving mechanism connected with one of the shafts, the tracks located above the conveyorbelt, and the pallets having stems secured to the chains of the conveyer-belt and provided with hangers having rollers running on the tracks, substantially as described.

2. The combination of supporting-frames, the vertical shafts, a pair of horizontal sprocket-wheels on eachv of the shafts, a conveyerbelt consisting of two endless chains, connecting the sprocket-wheels, a horizontal shaft and gear-wheels connecting the vertical shafts, driving mechanism connected with one of the shafts, the outer. broad track, the inner narrow track, and the pallets having stems secured to theA chains of the conveyor-belt and provided with outer hangers having rollers formed with broad treads, and inner hangers proj ectin gdownward for engaging the narrow track, having rollers formed with narrow treads, substantially as described.

3. The combination of supporting-frames, the vertical shafts, a pair of horizontal sprocket-wheels on each of the shafts, a conveyorbelt censistin g of two endless chains, connecting the sprocket-wheels, a horizontal shaft and gear-wheels connectingthe verticalshafts, drivi-ngmechanism connected with one of the shafts, the outer and inner tracks, and the pallets having :stems secured to the `chains of the conveyer-belt `and provided with hangers having rollers running on the tracks and with scraperslodated at diagonally-opposite corners of the pallets, substantially as described.

4. The combination, with the belt of a conveyer, of a pallet having a pendent stem secured to the belt,a hanger having a broad roller, :a .hanger having la narrow roller and having its endsextendin g beneath the roller, and the Scrapers located at diagonally-opposite corners'of the pallets,substantially as `described.
